PLANTING and AFTERCARE GUIDE

Best Planting Time

• Spring: The ideal time to plant Trollius x cultorum ‘New Moon’ is in spring as the soil begins to warm. This allows the roots to establish firmly before flowering, resulting in strong and healthy growth.
• Autumn: You can also plant Trollius in early autumn. This gives the plant time to settle before dormancy, encouraging vigorous growth the following spring.

Site Selection

• Sunlight: Trollius x cultorum ‘New Moon’ grows best in full sun to partial shade. Choose a spot that receives morning sun with some afternoon shade to prevent the soil from drying out.
• Soil: This perennial prefers moist, well-drained soil enriched with organic matter. It performs beautifully near water features, stream edges, or damp borders where conditions remain consistently moist but not waterlogged.

Planting Instructions

1. Prepare the Hole: When planting Trollius x cultorum ‘New Moon’, dig a hole twice the width and the same depth as the root ball to allow for comfortable root growth.
2. Soil Preparation: Mix compost or well-rotted manure into the soil to enhance fertility and retain moisture. This will support lush foliage and abundant blooms.
3. Planting: Position the plant so that the crown sits level with the soil surface. Backfill gently, firming the soil around the base to remove any air pockets.
4. Watering After Planting: Water thoroughly after planting to settle the soil around the roots and encourage strong establishment.

Watering Requirements

• Growing Season: Keep the soil consistently moist during the growing season. Trollius x cultorum ‘New Moon’ dislikes dry conditions, so regular watering is essential, particularly in warm periods. Avoid allowing the soil to dry out completely.
• Dormant Season: During dormancy, reduce watering but ensure the soil never becomes bone dry. Mulching helps retain moisture during this time.

Feeding

• Spring: Apply a balanced, slow-release fertiliser in early spring to encourage healthy growth and vibrant flowers.
• Mid-Summer: After flowering, a light feed of liquid fertiliser helps Trollius x cultorum ‘New Moon’ replenish energy reserves for the next season.

Pruning

• Deadheading: Remove spent flowers regularly to prolong the blooming season and maintain a tidy appearance.
• Autumn Pruning: Once flowering is complete and foliage begins to die back, cut down to ground level. This tidies up the plant and prepares it for winter rest.

Mulching

• Spring: Apply a generous layer of organic mulch such as compost or leaf mould around the base of your Trollius to retain soil moisture, regulate temperature, and suppress weeds.
• Winter: Mulching in late autumn also provides insulation to protect the roots from cold and helps the plant emerge strongly in spring.

Supporting the Plant

• Staking: Generally, Trollius x cultorum ‘New Moon’ has sturdy stems and maintains an upright form, so staking is rarely needed. However, in exposed sites, light staking can help prevent wind damage to the tall flower stems.
